ASSlGNORS TO INTERNATIONAL HARVESTER COMPANY, A COR- PORATION OF NEW JERSEY.

Specification of Letters Patent.

Application filed December 26,1905. Serial No. 293,177.

To all whom it may concern.-

Be it known that we, SAMUEL K. DENNIs and FRANK W. RICE, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Reel-Adjusting Mechanism for Harvesters, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

Our invention relates to reel-adjusting mechanism for harvesters, its object being to provide a simple, strong, and effective construction having operative means designed to positively adjust the reel to the various positions in which it may be operated, and the mechanism is particularly designed and applicable for use in connection with that type of harvesters in which the propelling means comprises what is commonly called a push-pole, upon which are munted various hand-operated levers having connections with the operative parts of the machine, which are not shown and may be any of the usual forms, as preferred.

In the accompanying drawings, Figure 1 is an end view of the reel-adjusting mechanism and as much of a harvester thought to be sutlicient to illustrate the application of our invention. Fig. 2 is a rear view of a part of the adjusting mechanism. Fig. 3 is a top plan view of part of Fig. 2. Fig. 4 is a partial side elevation of the adjusting means, and Figs. 5, 6, and 7 represent details of various parts.

The same reference characters represent similar parts throughout the several views.

The wheel-frame of the harvester comprises a push-pole 1, suitably connected at its forward end with an axle 2, and 3 is a tilting lever secured to the axle and adapted to rock it about its axis in a well-known way.

4 is the grain-platform, having rearwardlyextending frame members connected with the axle and supported thereby. Secured to the rear sill (i of the grain-platform are vertically-arranged posts 7, 8, and 9 and a part 10, forming a portion of the elevator-frame, and mounted thereon in a manner to be rocked about their axes are the tubular pipes 11 and 12 at the upper ends and near the center of the posts, respectively.

Mounted upon the pipe 11, near opposite ends thereof, are angle-bars 13 and 14, ex tending forwardly and rearwardly therefrom and adapted to rock thereon, and lateral braces 15 and 16 have their rear endssecured to the pipe 11 by means of the sleeves 1.7 and 18, loosely embracing the p pe, and their forward ends may be secured in any :nianncr to the forwardly-extending ends of the anglebars 13 and 14 and operate to hold the bars in correct angular relation with the pipe, and truss-rods 19 and 20 in comb'nation with suitable struts 21 and 22, forming a part of the connection between the angle-bars and the pipe, operate as supplemental supports for the extended ends of the bars.

Mounted upon the forward ends of the angle-bars is a reel supporting and drwing shaft 23, adapted to move in a fore and aft direction thereon by means of the journalboxes 24, having slidable connection therewith. Secured to the pipe 11, near opposite ends thereof, are levers 25, and 26 represents links pivotally connecting the outer ends of the levers with the slidable ournal-boxes, and near the central part of the pipe is secured a lever 27, having one end oi a link 28 pivotally connected with the outer end thereof, and the opposite end of the link may be connected with any of the common forms of handoperated levers located at the rear end of the push-pole and convenient to the hand of the operator for the purpose of rocking the pi )e 11 upon its axis, and thereby adjusting the reel through its connections with the pipe in a fore and aft direction relative to the grainplatform.

Secured to the )ipe 12 near its central portion is an upwarr l v-cxtending lever 29, and near opposite ends of the pipe are secured rearwardly-extending levers 31), having a series of openings at their outer ends concentrically arranged relative to the axis of the pi 1c, and 31 represents links pivotally connecter with the rearwardly-extended ends of the angle-bars 13 and 14 and the levers 31), the series of openings therein providing means for adjusting the connection between the pipe and said angle-bars. Adjustably secured to the levers by means of the threaded links 32 are countcrbalancing-springs 33, that have their Opposite ends secured to a fixed part of the grain-platform and operate to countcrpoisc the weight oi the forward ends of the reelsupporting bars and attached reel. Pivotally connected with the outer end of the lever 29 is a link 34, which may have its opposite end connected to any of the well-known forms of hand-operated levers, that may be mounted on the pole convenient to the hand of the operator. The ipes 11 and 12 may be rocked independentlf in either direction by ap )lying force to the respective links connected to the operating-levers secured thereto. \Vhen the pipe 11 is rocked, it communicates motion to move the reel in a fore and aft direction, and if the pipe 12 be rocked in its bearings it operates to raise or depress the reel-carrying arms and cause the reel to assume a higher or lower plane.

What we claim as our invention, and desire to secure by Letters Patent, is-- 1. In a reel-adjusting mechanism for harvesters, the combination of a grain-platform having vertically-arranged frame members secured to the rear side thereof, a rock-shaft mounted in bearings secured at the upper ends of said frame members, reel-supporting bars mounted at opposite ends of said rockshaft extending forward and rearward therefrom and adapted to rock about its axis, a reel-shaft slidably mounted upon the forward ends of said bars, arms secured to said rock-shaft and connected with said reel-shaft in a manner to move said reel-shaft in a fore or aft direction when said rock-shaft is rocked in its bearings, and a second rock-shaft mounted near the central portion of said frame members, having arms secured thereto and said arms having a link connection with the rear ends thereof said reelsupporting bars in a manner to rock said bars about their bearings when said rock-shaft is operated.

2. In a reel-adjusting mechanism for harvesters, the combination of a grain-platform. having vertically-arranged frame members secured to the rear side thereof, bearings secured to said frame members near the up er ends thereof at opposite ends of said pl fitform, reel-supporting bars mounted on said bearin s and adapted to rock thereon and extend lng rearward and forward therefrom, said bars having a reel-su )porting shaft mounted in bearings at their forward ends, a rock-shaft mounted in bearings secured to said vertically arranged frame members, arms secured to said rock-shaft near opposite ends thereof, link connections between said arms and the rear ends of said bars, and counterbalarming-springs having one end secured to a fixed part of the platform and their opposite ends connected with said arms in a manner to operate as a counterpoise for the weight of the reel mechanism.

3. In a reel-adjusting mechanism for harvesters, the combination of a grain-platform having vertically-arranged frame members secured to the rear side thereof, bearings secured to said frame members near the up er ends thereof at opposite ends of said pfatform, reel-supporting bars mounted on said bearings and adapted to rock thereon and extending rearward and forward therefrom, said bars having a reel-supporting shaft mounted in bearings at their forward ends, a rock-shaft mounted in bearings secured to said vertically-arranged frame members, arms secured to said rock-shaft near opposite ends thereof, said arms having a series of openings concentrically arranged relatively to the axis of the shaft, links adapted to engage with said openings and connect said arms with the rear ends of said reel-supporting bars, and counterbalarming-springs having one end secured to a fixed part of the platform and their opposite ends adjustably connected with said arms.

In witness whereof we hereto aflix our signatures in presence of two witnesses.
